Run The Jewels were in the studio with Massive Attack yesterday, as Pitchfork points out. “So… no big deal or anything. not bragging a lot. just talking here,” El-P tweeted. Killer Mike followed that up with a pair of Instagrams of the two duos working together. “In studio with @massiveattack vibe’n to #BruceSpringsteen n Such. What y’all doing? What ever it is, let it be Grand y’all! Salutes,” he wrote. No clue what they’re doing together — hopefully a possible collaboration for RTJ3? Check out video of them vibing to Bruce Springsteen below.
